Care Management Terminology and Glossary

Care management operates within a dense regulatory and clinical vocabulary that shapes how services are authorized, reimbursed, documented, and evaluated across the US healthcare system. This page defines the core terms used in care management practice, policy, and billing — drawing on definitions from federal agencies, accreditation bodies, and published clinical standards. Precise terminology matters because misapplication of terms can affect Medicare and Medicaid reimbursement eligibility, affect quality measure reporting, and create documentation gaps in care planning.

Definition and scope

Care management is defined by the Centers for Medicare & Medicaid Services (CMS) as a set of activities intended to assist patients and their support systems in managing medical and behavioral conditions, with the goal of improving outcomes and reducing unnecessary utilization (CMS Innovation Center). The term encompasses a wide spectrum of roles, settings, and intensities — from brief telephonic outreach to long-term complex care management for patients with multiple chronic conditions.

Key terms that define the field:

  1. Care coordination — The deliberate organization of patient care activities and information-sharing across participants to achieve safer and more effective care. The Agency for Healthcare Research and Quality (AHRQ) distinguishes care coordination from care management by framing it as a mechanism rather than a program (AHRQ Care Coordination).
  2. Case management — A collaborative process of assessment, planning, facilitation, care coordination, evaluation, and advocacy. The Case Management Society of America (CMSA) holds the primary definitional authority for this term in the US (CMSA Standards of Practice).
  3. Transitional care — Structured support provided across care settings, typically spanning 30 days post-discharge. CMS Transitional Care Management (TCM) codes (CPT 99495 and 99496) define reimbursable transitional care activity (CMS TCM Billing Guide).
  4. Chronic care management (CCM) — A Medicare program established under the Physician Fee Schedule that reimburses non-face-to-face care for beneficiaries with 2 or more chronic conditions expected to last 12+ months (CPT 99490). See chronic disease care management for program structure.
  5. Utilization management (UM) — A function focused on appropriateness, medical necessity, and efficiency of healthcare services. The National Committee for Quality Assurance (NCQA) sets utilization management accreditation standards under its Health Plan Accreditation framework (NCQA).
  6. Population health management — A model in which care is organized around defined patient cohorts based on shared risk characteristics, geographic boundaries, or payer enrollment. See population health management for definitional framing.
  7. Risk stratification — A clinical and administrative process of grouping patients by probability of high-cost utilization or adverse outcomes, typically using algorithms applied to claims or EHR data.
  8. Care plan — A structured, individualized document identifying goals, interventions, and responsible parties across the care team. CMS requires care plans for CCM participation and mandates patient access to the plan.

How it works

Terminology in care management functions within a structured hierarchy: federal statutes define program eligibility and billing codes; accreditation standards (NCQA, URAC, JCAHO) define operational quality benchmarks; and professional certification bodies (CMSA, Commission for Case Manager Certification/CCMC) define scope-of-practice vocabulary.

The vocabulary flows through 3 layers:

  1. Regulatory layer — CMS CPT codes, ICD-10 diagnostic categories, and federal program rules (Medicare Advantage, Medicaid managed care). Definitions at this layer determine reimbursement.
  2. Accreditation layer — NCQA's Case Management Accreditation program, URAC's Health Utilization Management standards, and The Joint Commission (TJC) standards for care coordination. These define operational terms such as "interdisciplinary team," "care transition," and "functional assessment."
  3. Certification layer — CCMC's CCM Certification Guide and CMSA's Standards of Practice for Case Management establish scope-of-practice definitions used in licensure, credentialing, and litigation contexts.

Understanding which layer applies determines how a term must be used in documentation. For example, "care coordinator" carries no federal licensure requirement but carries specific credentialing weight under NCQA accreditation criteria.

Common scenarios

Chronic disease billing documentation: A practice billing CPT 99490 (CCM) must document at least 20 minutes of non-face-to-face care per calendar month. The term "non-face-to-face" is defined in CMS billing guidance and excludes time spent during Evaluation and Management (E&M) visits.

Applying the wrong code is a documentation compliance issue under Medicare Part B.

Behavioral health integration: The term "collaborative care" has a specific billing definition under CMS (CPT 99492–99494) distinct from general behavioral health care management. See behavioral health care management for the distinction.

Risk stratification in care management: Payers and ACOs typically apply 3-tier stratification models (low, moderate, high risk) aligned to NCQA or CMS quality benchmarks, though the specific criteria vary by program and algorithm.

Decision boundaries

Care management vs. case management: CMS and AHRQ treat care management as a broader programmatic term; case management refers to an individualized, episode-oriented role defined by CMSA and CCMC. The care coordination vs. care management page addresses this distinction in operational terms.

Utilization management vs. care management: UM is primarily a payer-side authorization function governed by URAC and NCQA standards; care management is a provider- or payer-side clinical support function. The two overlap in managed care but carry distinct accountability structures.

When terminology triggers compliance requirements: Use of the term "care plan" in a CMS-billed service triggers specific documentation mandates. Use of "medical necessity" in UM determinations triggers state insurance code requirements and ERISA obligations for employer-sponsored plans.

For accreditation and certification definitions, case management certification requirements outlines the credentialing body standards that govern scope-of-practice vocabulary.
